In reply to bpmclimb:
Ok, I've had a closer look at the logbooks, and still think that many, if not all of the earlier ascents were of the harder line - it was the only legit line which "officially" existed until much more recently. On balance, probably the majority of logged ascents.
Whatever I do is going to result in many logbook entries being wrong, but I've made the version with 800+ logs the original and direct; and made the new entry the 6a+ indirect version.
One problem which persists is that I can't change the grade of 6b because that's whats in the Rfax database. Can we make it 6b+ at least, please?
Thanks
